1 Gigawatt = 1000 Megawatt

Key Formulas

Kilowatt → Horsepower (mech)

hp = kW × 1.34102

Horsepower (mech) → Kilowatt

kW = hp × 0.7457

Watt → Kilowatt

kW = W × 0.001

Kilowatt → Watt

W = kW × 1000

Formula

MW = GW × 1000

Policy targets are set in gigawatts; power plants are built in megawatts. When a government announces a 50 GW offshore wind target, developers break it into individual projects: 50,000 MW means roughly 5,000 turbines at 10 MW each. Grid planners also use GW-to-MW when comparing national transmission capacity (GW) to individual corridor ratings (MW), making GW-to-MW the most commonly used scale transition in power system planning.

Frequently Asked Questions

Real-World Examples

A 1 GW national energy target = 1,000 MW — achievable with five 200 MW solar farms or ten 100 MW wind projects.

1 GW = 1000 MW

A 50 GW renewable energy target = 50,000 MW — the scale of a major national energy transition requiring thousands of projects.

50 GW = 50000 MW

A 0.5 GW regional grid tie = 500 MW of interconnector capacity — a typical high-voltage DC link between neighboring countries.

0.5 GW = 500 MW

A 3 GW pumped hydro storage facility = 3,000 MW of dispatchable power — the backbone of grid balancing in mountainous regions.

3 GW = 3000 MW
